Tóm tắt

The article introduces self-made galvanized steel mesh (SGSM) from reinforcement type CB 300V. Numerical simulation of retaining walls at the Tran Thi Ly overpass intersection in Da Nang City when using SGSM and three other popular types of reinforcement, and calculating the construction cost of the wall when using these types of reinforcement. The results show that using SGSM is more technically and economically efficient than using other types of reinforcement currently being imported. Specifically, after wall construction and when loading 400 kN/m2, it shows that using SGSS, the factor of safety is higher (Fs=3.85 and Fs=1.34), mobilizing more tensile force in the reinforcement (13.21% and 88.65%) and lateral displacement of the wall facing is smaller (Δ=1.961 mm and Δ=32.01 mm), the total wall construction cost are 20.24%, 5.48% and 1.76% lower than polymeric reinforcement strip, polyester geotextile mesh and galvanized flat steel strip.
